Based solely on feeding response, I see no issue at all. Kings are garbage disposals and I have never run into feeding issues with any of my Kings.

However, I personally would NOT run my king temps that high. You've got some great people offering experience and knowledge about your temps because they genuinely care about the animals. Your original question was vague and people offered insight based on that. That's why temps came into play with their answers. Then you came back with the temps aside thing saying your only concern was feeding response. Well, you absolutely SHOULD be concerned with temps and I would NOT advise keeping Kings at those temps you mention. I have been keeping Kings for years and my temps never get higher than mid 80s.
